THRESHlNG-MACHINE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 734,751, dated July 28,1903. Application filed September 11, 1902. Serial No. 123,007-(Remodel-l To all whom it may concern; Be it known that 1, CHARLES L.RICHARDS,

a citizen of the United States, residing at Falun, in the county ofSaline and State of Kansas, have invented a new and useful Threshing-Machine Attachment, of which the following is a specification. xThis invention relates to band-cutting and feeding'attachments forthreshing-machines;

and it has for its object to provide a device of this class which shallpossess superior advan tages in point of simplicity, durability, and

general efficiency.

With these ends in View the invention con? sists in the improvedconstruction, arrange ment, and combination of parts, which will behereinafter more fully described, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a sectional elevationillustrating myinvention applied to a threshing-machine in operativeposition. 2 is a plan View showing the cutter-bars, the shaftssupporting the same,

and related parts. Fig. 3 is a sectional elevation taken on the line 3 3in Fig. 2.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

4 designates the feed-table, the upper side of which is preferablyserrated, asshown at 5, and which is disposed to receive the usualvibratory motion by means not illustrated in the The front end of thefeed-tableis supported upon a portion of the casing, as 6.

7 designates a crank-shaft which is supported in suitable bearings inthe sides of the casing and which is provided between said sides withtwo cranks 8 8, extending in opposite directions from the axial line ofthe shaft. This shaft is provided at one of its extended ends with apulley 9, by means .of which it receives motion from the source, ofpower. At

its opposite end the said crank-shaft carries a governor 10 to regulatethe speed thereof. This governormay be of any suitable approvedconstruction, and as it forms no part of my present invention it doesnot need to be described in detail.

1 designatesa part of the casing of a threshing-machine, of which 2designates the cylin A pair of cutter-bars 11 are supported by,

means of boxes 12 upon the cranks 8 of a shaft 7. Each of thesecutter-bars is composed of three separate pieces 13 1414:, the frontsection 13 of each cutter-bar being interposed between the front ends ofthe adjacent sections 14 14, beyond which it. extends, .as will beclearly seen in- Fig. 2 of the drawings. The rear ends of the saidcutter-bars are supported by means of stirrups or links 15, provided attheir ends with cranks 16, engaging boxes 17,

that are suitably supported under the top of the frame or casing of themachine, said st-irrups'being journaled in boxes 18 upon the rear endsof the members 14 of the cutter-bars.

"of perforations 23 to receive the fastening pin or bolt 23.

24 designates the endless carrier, which may be said to constitutethefeed-table proper and upon which the sheaves are placed in'position tovpass under the cutters and under the vi brating pan 4, from which thegrainkis fed to the cylinder. This endless carrier is supported upon thefront and rear shafts, .de signated, respectively, 25 and 26, the latterof which may be withdrawn and replaced in; auxiliary bearings 27, so asto raise orl lowerj the rear end of said carrier, as may be found;

necessary .or I desirable. justably connects the front end ofthe'endless carrier with the framing or casing of the machine, and it ispreferred to construct the A brace-rod 28 ad said carrier with a hinge29, which shall enable said carrier to be folded while in transit. Therear ends of the compound cutter barsare provided with feed-plates 30,which may be constructed either of wood or metal and which are providedwith deep cuts or serrations, as 31, which being disposed directly abovethe rear discharge of the endless carrier and above the vibratory pan 4:will greatly assist in feeding the grain to and preventing it frompassing over the cylinder. These plates are firmly secured to the sidesof the rear ends of the members 14 of the cutterbars, and provision maybe made, if desired, for the vertical adjustment of the rear ends ofsaid feed-plates for instance, by providing them with slots 82 for thepassage of the clamping-bolts 33.

It will be observed that by the construction and arrangement of partsherein shown and described each cutter-bar is provided with a set offour band-cutters disposed equidistantly laterally, while two of theband-cutters of each set are disposed in front and in rear of the tworemaining ones, the arrangement being such, as will be seen by referenceto the drawings, that the band-cutters secured to the outer sides ofeach cutter-bar are in alinement with each other, while those secured tothe central member of each cutterbar or between said central member andthe outer members are disposed, respectively, in front and in rear ofthe outside cutters, thereby covering a large area and making itpractically impossible for a single sheaf to pass the device withouthaving its band out. This is a matter of considerable importance,inasmuch as serious accidents are frequently caused by the attempt tocut the bands of sheaves in transit which have escaped the band-cuttingmechanism. The feed-plates are likewise disposed in the positions inwhich they may most effectively exercise the functions for which theyare provided.

The operation of this invention and its advantages will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed. The crank-shaft imparts to the cutter-barssupported thereon a forwardly and rearwardly', as well as an upwardlyand downwardly, reciprocating motion, whereby the cutters mounted uponsaid bars are caused to cut the bands of the sheaves fed underneath themby means of the endless carrier 24:, upon the front end of which theyare placed by the operator. The speed of the crank-shaft 7 will begoverned by the governor 10. The discharge end of the endless carriermay be adjusted vertically, so as to bring its upper or carrying surfaceat a greater or less distance from the band-cutters and the grain,

central member and rearwardly-extending outer members, said membersbeing firmly connected together, and cutters secured adjustably to theouter sides of the outer members and to the outer sides of the centralmember, the cutters secured to said central member being disposedrespectively in front and in rear of those secured to the outer members.

2. In a device of the class described, a cutter-bar composed of aforwardly-extending central member and rearwardly-extending outermembers, said members being firmly connected together, cutters securedadjustably to the outer sides of the outer members and to the outersides of the central members, the cutters secured to said central memberbeing disposed respectively in front and in rear of those secured to theouter members, a crank-shaft supporting the front ends of saidcutter-bars, feed-plates secured to the outer sides of therearwardly-extended mem-.

bers, and stirrups connecting said rearwardlyextended members of thecutter-bars flexibly with the frame of the machine.

3. In a device of the class described, a cutter-bar composed of aforwardly-extending central member and rearwardly-extending outermembers, said members being firmly bolted together and carryingband-cutting knives, in combination with downwardlyextending serratedteeth-plates secured to the outer sides of the outer members at the rearends thereof, and means for adjusting the dip of said serrated plates.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
